Are My measurements Right?

[rgibsonx2]

In the hallway of our Historic Courthouse, we have an extensive Native American basket display. The interior lighting in the cases is with fiber optic lighting, but the hallway was lit by five 12 bulb incandescent chandeliers. The county recently replaced the incandescent bulbs with CFLs. We cried foul and immediately borrowed a UV light meter (which measure in microwatts per centimeters squared) and a regular light meter (which measures in footcandles). The UV levels I measured ranged from 900 to 1500 microwatts per lumen, which seems awfully high.

As an example: On one case we measured 7 microwatts of UV per square cm with the UV meter. We then measured 4.6 footcandles of light on the same case.

I converted the footcandles to Lux (4.6 x 10.76 = 49.5). Then I converted the microwatts per square cm to microwatts per square meter (7 x 10,000 = 70,000). I then dvided the Lux into the microwatts per square meter to get the microwatts per lumen (1414).

Is there perhaps an accumulative effect with UV? Or am I way off in my calcualtions or formula?

Any guidance would be greatfully appreciated!
